Mechanical property tester for biological soft tissues

Disclosed is a mechanical property tester (100) for biological soft tissues, comprising a frame (10), a test head holder (20), a tested object fixture base (30), an acquisition device, a computer, at least two groups of test heads (50), at least two groups of fixtures (60), at least two groups of displacement sensors and at least two groups of pressure sensors (70), wherein the tested object fixture base (30) is arranged on a working platform (11) of the frame (10), one of the at least two groups of test heads (50) is selectively mounted on the test head holder (20), one of the at least two groups of pressure sensors (70) is selectively mounted on the test head holder (20), one of the at least two groups of displacement sensors is selectively mounted on the frame (10), one of the at least two groups of fixtures (60) is selectively mounted on the tested object fixture base (30), the acquisition device acquires the pressure value detected by the pressure sensors (70) and acquires the displacement detected by the displacement sensors, and the computer is connected to the acquisition device through signals to analyse the pressure value and the displacement. The mechanical property tester for biological soft tissues has the effects of tested object diversity, implementation of a variety of test functions and cost reduction.
